Release Notes: All the remaining obsolete functions from GTK+ 1.x
have been replaced with the new functions from
GTK+ 2.0. The threading and semaphores have been
ported from the pthreads library to the glib 2.0
library. This is the official GTK+ 2.0 stable
release.

Release Notes: This release fixes a semaphore initialization bug (a thread could be
waiting for a semaphore that wasn't initialized), several serious
potential buffer overflow bugs, and other minor bugs.
